Insulating cover for an attic sealing member

ABSTRACT

An insulating system comprises a cover and a generally rigid attic sealing member. The cover defines an interior chamber, and the interior chamber is filled with insulation. The cover further forms a cavity in the bottom of the cover, where the attic sealing member is received into the cavity. Together, the system raises the insulating value (R-value) of an area above an attic opening to a minimum R-value level required by many building codes. The cover may be filled with insulation through a slit or passage extending along the top of the cover.

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to an insulating system for use in buildings. More particularly, the present invention relates to an insulating cover for insulating attic openings. Specifically, the present invention relates to an insulating cover configured to fit over and receive therein a generally rigid sealing member atop an attic opening.

2. Background Information

Houses are commonly provided with a pull-down foldable ladder providing access to an attic. The attic opening is provided with a spring-loaded door which is pivotally mounted at one end. The foldable ladder is mounted to the top side of the door and such offers support to the ladder when it is unfolded, the foot of the ladder resting on the floor of a hallway or a room. The door is provided with a rope on the bottom side to pull the door downwardly so that the ladder can be unfolded to provide access to the attic.

The closure is generally located between two joists so that when the ladder is in a folded mode, it is located between the joists. Although insulation is commonly provided between the joists in the attic, for obvious reasons it is believed, the area surrounding and over the ladder is not. Moreover, it will be appreciated that the attic closure does not, in and of itself, provide a good seal with the opening in the attic floor. Thus, there is a crack or void through which hot air can be lost from the house in the winter and cold air in the summer, if the house is air conditioned. The heat loss through the stairwell, even though the area not provided with insulation is small, is considerable particularly in the colder climates. This, of course, results in greater heating bills. In a similar manner, an air-conditioned or cooled home in a warmer climate can allow hot air to flow into the living space, particularly, this leads to greater costs to cool the air conditioned home.

To combat these problems, devices are known to exist that cover attic openings, and many devices are known to cover attic openings having staircases in the folded position. Exemplary proposed solutions of others to combat these problems are shown in U.S. Pat. Nos. 5,628,151; 4,281,743, 4,658,555, 5,475,955, 4,151,894, 4,832,153; as well as in U.S. Pat. App. Publ. Nos.: 2004/0055819; 2013/0219804; and in a device commercially available for sale, known as a Therma-Dome® by Yankee Insulation Products, LLC of New Boston, N.H.

SUMMARY

Although these devices are somewhat satisfactory in insulating attic openings, in real world applications issues continue to exist with their insulation properties inasmuch as they still lack the insulation rating (R-value) equivalent of the surrounding attic floor space. One way of combating these problems associated with the relatively low R-value of the above mentioned devices is draping loose insulation over or affixing it to such insulating cover units. However, this option does not ensure that the insulation remains in place when the cover is moved, and it does not guarantee a completely effective insulative barrier, since any voids in the insulation will diminish the desired effect of any additional insulation placed thereon. The present invention addresses these and other issues.

In one aspect, the invention may provide a manner in which an individual that is concerned about maintaining a consistent insulation rating between attic floor space and the area over attic openings may do so by neatly and evenly applying additional insulation to an attic opening cover. One embodiment of the invention may provide a preformed containment area, which allows the individual to install one of a number of types of insulation (including, but not limited to fiberglass batt or blown-in cellulose insulation), to an even and consistent depth on all sides of the attic opening cover.

In another aspect, an embodiment of the present invention is configured to meet the need for supplemental insulation as required by building code requirements or individual preference when a standalone device, such as an attic cover lacks the required R-value. An embodiment of the invention may provide a cover having preformed panels to fit snugly over an existing attic opening cover, and will form a container that allows an even distribution of an insulating material on the top and each of the four outer sides (or any combination thereof) of the existing attic sealing member.

In another aspect, the invention may provide an insulating cover to insulate an area above an attic opening, the cover comprising: a plurality of connected walls creating a box-like structure; an interior chamber defined by the inner surfaces of connected walls, said interior chamber adapted to house insulation therein; and a cavity defined by the outer surfaces of connected walls, the cavity adapted to receive a generally rigid attic sealing member at least partially therein.

In another aspect, an embodiment of the invention may provide an insulating system for placing within an attic above an opening, the system comprising: a generally rigid attic sealing member; and a cover defining a chamber therein for filling with insulation, and a cavity formed by the outer surface of the cover, wherein the sealing member is received at least partially in the cavity.

DETAILED DESCRIPTION

As shown throughout the Figures, an insulation system 1 comprises an insulating cover shown as 10 in FIGS. 1-6; shown as 110 in FIG. 7; and shown as 210 in FIG. 8. System 1 further comprises a generally rigid attic sealing member 12 and an attic opening 14. Insulating cover 10 receives a portion of member 12 therein to cover generally rigid member 12 when member 12 is in a sealing position atop attic opening 14. Cover 10 is configured to be filled with insulation 46.

With primary reference to FIGS. 1-6, cover 10 includes a top panel 16 spaced apart and generally parallel to a bottom panel 26 that defines a vertical direction therebetween. Top panel 16 faces vertically upward and bottom panel 26 faces vertically downward. Cover 10 includes a first sidewall 18 spaced apart and preferably generally parallel to a second sidewall 20 that defines a lateral direction therebetween. Cover 10 includes a first endwall 22 spaced apart and preferably generally parallel to a second endwall 24 that defines a longitudinal direction therebetween.

Endwalls 22, 24 intersect sidewalls 18, 20 in a generally perpendicular manner to define a generally box-like structure. Top panel 16 and bottom panel 26 connect to sidewalls 18, 20 and endwalls 22, 24 to respectively define the top and bottom of the box-like structure. Cover 10 defines a fillable and hollow chamber 44 therein. While it is preferable in this embodiment that sidewalls 18, 20 are generally parallel, there may be instances where sidewalls 18, 20 are not parallel. For example, some generally rigid members 12 known to exist in the art are not rectangular in shape, they are trapezoidal. If generally rigid member 12 is trapezoidal, then clearly sidewalls 18, 20 will not be parallel either to allow cover 10 to properly fit over member 12.

Cover 10 is preferably a substantially non-rigid and at least semi-flexible structure, yet there may be some semi-rigid components as described below. In one particular embodiment, top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 are constructed of a polymer based flexible material such as an LDPE (polyethylene film). Alternatively, a fabric or non-woven fabric (NWF) could be used to construct the top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 that define cover 10. Further, while it is preferable that top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 are flexible, it is clearly possible that top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 may be semi-flexible or generally rigid to define chamber 44. The material thickness of top and bottom panels 16, 26, sidewalls 18, 20 and endwalls 22, 24 of cover 10 is sufficient to hold insulation 46 in chamber 44 without adding unnecessary weight of system 1 by creating an unnecessarily thick cover 10. Seams (unnumbered) extending along the intersection of respective panels and walls of cover 10 are formed using a heat-seaming device (not shown) to seal overlapping segments of adjoining panels, however it is clearly contemplated that other manners of forming seams are entirely possible as one having skill in the art would understand. If cover 10 is a NWF, the seams could need to be stitched or heat-seamed or formed in another manner as one having skill in the art would understand.

In a exemplary embodiment for covering an attic staircase opening, cover 10 has the following non-limiting dimensions when filled with insulation 46: a longitudinal length measured endwall 22 to endwall 24 from about 70 to about 85 inches; a lateral width measure sidewall 18 to sidewall 20 from about 40 to about 50 inches; and a vertical height measured top panel 16 to bottom panel 26 from about 15 to about 25 inches.

As shown in FIG. 4, cover 10 further includes walls that extend inwardly into chamber 46 from bottom panel 26 to define a cavity 40. Namely, two longitudinally extending inner sidewalls 30, 32 are spaced apart between two laterally extending inner sidewalls 34, 36. Inner sidewall 30 is generally parallel to sidewall 20 defining a portion of chamber 44 therebetween. Inner sidewall 32 is generally parallel to sidewall 18 defining a portion of chamber 44 therebetween. Inner endwall 34 is generally parallel to endwall 24 defining a portion of chamber 44 therebetween. Inner endwall 36 is generally parallel to endwall 22 defining a portion of chamber 44 therebetween. An upper inner panel 28 defines the top of cavity 40. Upper inner panel 28 is generally parallel with top panel 16 defining a portion of chamber 44 therebetween. By way of non-limiting example, the outer surfaces of inner sidewalls 30, 32, inner sidewalls 34, 36, and upper inner panel 28 on cover 10 define cavity 40.

With primary reference to FIG. 5, a slit or passage opening 42 extends along top panel 16. Slit 42 is configured to permit access into and egress out of chamber 44 (FIG. 6). Slit 42 preferably includes overlapping segments formed in panel 16. The overlapping segments of passage 42 may have securing members affixed thereto, such as adhesive or hook-and-loop closures to retain the overlapping segments together. Alternatively, slit 42 may be closed by having zipper (not shown) attached to the respective edges that define slit 42. Furthermore, while reference is made to slit 42 being formed by overlapping segments formed in panel 16, it is to be clearly understood that the slit 42 may be located in any panel 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36 of cover 10 which would give an operator access to chamber 44.

Chamber 44 may be filled with blown insulation 46 by inserting hose 48 through slit 42. Alternatively, a non-blowable insulation 46, such as fiberglass insulation as understood in the art, may be inserted through slit 42 into chamber 44 by hand. Chamber 44 may have a depth configured to fit full sized R-30 fiberglass insulation. Preferably, Chamber 44 has a depth of about nine inches measured from top panel 16 to bottom panel 26. The nine inch depth is configured to accommodate R-30 fiberglass insulation, however the depth could vary to accommodate alternatively R-valued fiberglass insulations which would have associated thicknesses.

Insulation 46 is a conventionally acceptable form of attic insulation. Some non-limiting examples of insulation that may be used are fiberglass, mineral wool, plastic fiber, natural fiber, conventionally known batting, foam or foam board, cellulose, conventionally understood expanding insulation, or any variety of combinations thereof. Alternatively, if a non-blown insulation is used, such as a blanket or roll type, insulation 46 may be inserted into chamber 46 through slit 42 by hand. A non-limiting example of insulation 46 that may be used in system 1 is a R-30 fiberglass unfaced continuous roll, commercially known as EcoTouch™ available for sale by Owens Corning Corporation of Toledo, Ohio.

In exemplary embodiments, about twenty pounds of insulation 46 is used to fill chamber 44 by inserting the insulation 46 through slit 42. When using roll insulation 16 as described above, it is contemplated that the roll will be cut into various segments so the cut insulation segments can be laid within chamber 44. For example, a first set of two cut segments of roll insulation 46 have a width of about 15 inches and a length of about 62 inches. One of these two segments from the first set is disposed between a sidewall 18 and inner wall 32 within the chamber 44. The second of these two segments from the first set is disposed between sidewall 20 and inner wall 30 within the chamber 44. A second set of two cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 46 inches. One of these two segments from the second set is disposed laterally between endwall 22 and inner wall 36 within chamber 44. The second of these two segments from the second set is disposed between endwall 24 and inner wall 34 within chamber 44. A third set of three cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 78 inches. Each of the cut segments are disposed longitudinally side-to-side and positioned below top panel 16 and above the first set, the second set, and the upper inner wall 28 within chamber 44. When arranged in the above described manner, flexible cover 10 retains the shape of the laid insulation 46 segments.

As depicted in FIG. 6, the bottom edges of inner sidewalls 30, 32, 34, 36 define a cavity opening 38. The bottom edges defining opening 38 are spaced laterally and longitudinally inward of the bottom edges of sidewalls 18, 20 and endwalls 22, 24. Cavity opening 38 is in communication with cavity 40. Cavity 40 extends from opening 38 to upper panel 28. Inner upper panel 28 is positioned at a height above bottom panel 26 and vertically below top panel 16 when viewed from the side. Inner upper panel 28 and inner walls 30, 32, 34, 36 are also preferably made of a non-rigid material similar to sidewalls 18, 20 and endwalls 22, 24. However, it is clearly possible that inner upper wall 28 and inner walls 30, 32, 34, 36 may be generally rigid to define cavity 40.

With continued reference to FIG. 6, when cover 10 is placed above opening 14, cavity 40 is to the left of wall 30 and chamber 44 is to the right of wall 30. Cavity 40 is to the right of wall 32 and chamber 44 is to the left of wall 32. Cavity 40 is below wall 28 and chamber 44 is above wall 28. When viewed in cross section (FIG. 6) cover 10 is generally an inverted U-shape having a thickness, wherein the representative thickness is defined by chamber 44 and the space defined between the legs of the U-shape is cavity 40.

As shown throughout the Figures, cover 10 receives generally rigid member 12 at least partially in cavity 40. Rigid member 12 is also a box like structure configured to engage the attic floor 60 above attic opening 14. Rigid member 12 includes a generally rigid top panel 12 a, sidewalls 12 b, 12 c, and endwalls 12 d, 12 e, and a bottom wall 12 f. The rigid member walls define a rigid member cavity 12 g. In one non-limiting embodiment, generally rigid member cavity 12 g receives the attic staircase therein when the staircase is in a closed position. Alternative examples may be free of a staircase, such as when the cover 12 is placed atop member 12 placed above an attic scuttle opening.

In the example embodiment, when in the assembled position (FIG. 2 and FIG. 6) top panel 12 a is closely adjacent inner upper wall 28. Similarly, sidewalls 12 b, 12 c, are closely adjacent inner walls 32, 30, respectively. Additionally, endwalls 12 d, 12 e are closely adjacent inner walls 36, 34, respectively. In one embodiment, the respective walls engage each other via a frictional interference fit, however other conventionally understood ways of attaching, member 12 within cavity 40 of cover 10, such as via adhesive or hook-and-loop securing members, are contemplated. In one preferred example, member 12 is secured within cavity 40 of cover 10 by double-sided adhesive tape.

Elements of sealing member 12 are herein described relative to elements on cover 10. When viewed in cross section (FIG. 6), top panel 12 a is below upper panel 28 and at a height above bottom panel 26. Top panel 12 a is positioned inwardly within cavity 40 from inner walls 30, 32, 34, 36. Top panel 12 a forms the top of a generally inverted U-shape when viewed in cross section. Top panel 12 a on sealing member 12 is positioned generally directly above the access opening in the attic floor and in one particular example is positioned directly above a folded articulable attic access ladder.

By way of non-limiting example, rigid member 12 may be a Therma-Dome® commercially available for sale by Yankee Insulation Products, LLC of New Boston, N.H. Although the Therma-Dome® is the preferred rigid member 12, clearly other commercially available rigid members configured to seal an attic opening 14 may be used.

Commercially available rigid members are ordinarily lined with an insulating foil, which gives the generally rigid sealing member 12 an insulation value of about R-13. However, typically, many states set forth guidelines for a newly constructed or newly renovated attic to have an insulation value of about R-30, some states, such as Massachusetts for example have released weatherization assistance programs and technical manuals which suggest that attic insulation have an insulation value of at least R-38. The MASSACHUSETTS WEATHERIZATION ASSISTANCE PROGRAM TECHNICAL MANUAL recommends using a Therma-Dome® or equivalent (i.e., generally rigid sealing member 12) to be used whenever possible. See pages 61-62 of the MASSACHUSETTS WEATHERIZATION ASSISTANCE PROGRAM TECHNICAL MANUAL, the entirety of which is hereby incorporated by reference as if fully re-written herein and a copy of which may be obtained at http://www.mass.gov/hed/docs/dhcd/cd/wap/waptechnicalmanual.pdf at the time of filing this disclosure.

Thus, when the state codes require or guidelines suggest a certain R-value for the attic, cover 10 has an R-value to meet those thresholds in order ensure cover 10 R-value is similar to a surrounding attic floor R-value. In the non-limiting example stated above, if the surrounding attic R-value is R-38, cover 10 is filled with insulation so insulation system 1 has a resultant R-38 insulating value as well.

The following example relates to an attic opening 14 with a staircase, however it is understood that other attic openings may be covered with cover 10 atop member 12. Attic opening 14 is configured to receive a convertible and folding attic stair case therethrough. The attic opening 14 is defined by a conventional attic passageway frame to permit a homeowner access to the attic. A pull-down foldable ladder (unnumbered) provides access to the attic so a homeowner can climb the staircase and stand on the attic floor 60. The stairwell to the attic is provided with a spring-loaded closure which is pivotally mounted at one end. The foldable ladder is mounted to the top side of the closure and such offers support to the ladder when it is unfolded, the foot of the ladder resting on the floor of a hallway or a room. The closure is provided on the bottom side with a rope or other means for pulling the closure downwardly so that the ladder can be unfolded to provide access to the attic. The closure is generally located between two joists whereby the ladder in its folded mode is located between the joists.

With primary reference to FIG. 7, cover 110 provides an alternative way of permitting access to the chamber 144 for filling with insulation. Cover 110 includes a flap or door 116 selectively movable between an open and closed position. As shown in FIG. 7, door 116 may be pivotably opened about one side of door 116 pivotal connection to a sidewall. Door 116 may be securely closed by a securing member 102 when in the closed position. Securing member 102 is preferably hook-and-loop closures to retain the overlapping segments of securing member 102 together. Alternatively, securing member 102 may be closed by having zipper (not shown) attached or through the use of adhesive.

With primary reference to FIG. 8, cover 210 includes a plurality of interior compartments or segmented chambers 244 a, 244 b, 244 c, 244 d, and 244 e. The segmented chambers 244 a, 244 b, 244 c, 244 d, and 244 e permit a user to selectively fill and insulate the respective chambers. This is beneficial as there may be a scenario where one side of cover 210 is disposed closely adjacent to an attic wall (not shown) and a chamber may be selectively left empty to fit the space. Segmented chamber 244 a is positioned below the top panel and above the upper inner panel. Segmented chambers 244 b and 244 c are positioned opposite each other and extend longitudinally along each side of the inner walls that define cavity 40. Segmented chambers 244 d and 244 e are positioned opposite each other and extend laterally along each side of the inner walls that define cavity 40. Segmented chambers 244 a, 244 b, 244 c, 244 d, and 244 e may be filled with insulation during construction or assembly of cover 210.

Additional components may be included to further accomplish the purpose of system 1. By way of non-limiting example, a shape retaining member (not shown), like a belt or even a skeleton frame, may be included with system 1 to surround cover 10 to retain the shape of cover 10 when it is filled with insulation.

In accordance with one embodiment of the present invention, cover 10 is designed and configured to supplement and raise the total insulation value of the insulating ability of an existing attic sealing rigid member 12. Sealing member 12 atop opening 40 with a pull-down attic staircase ordinarily has an approximate R-13 insulative value. Cover 10 allows the customer to raise the R-value to R-30 or higher by covering the sealing member 12 and placing insulation 46 on all outside surfaces (sides, ends, and top) of the sealing member 12 within chamber 44 of cover 10. The combination of cover 10 with sealing member 12 will allow the sealing member 12 (which has a relatively low R-value and is insufficient to meet some building codes by itself) to be used in applications that require compliance with building codes that specify minimum R-38 insulation over attic access. Sealing member 12 includes a first insulating R-value and cover 10 for placing atop the sealing member includes a second insulating R-value larger than the first insulating R-value of sealing member 12. In one example, a first insulating R-value of the sealing member 12 is less than about R-20 and a second insulating R-value of the cover 10 is greater than about R-20.

In one particular embodiment, system 1 including cover 10 capping sealing member 12 has an insulating R-value that is at least R-38. In another example, system 1 may have a R-value (collectively cover 10 plus sealing member 12) as high as an R-45 rating, which is a significant improvement over the R-13 rating of member 12 alone. Notably, cover 10 of system 1 is preferably not a stand-alone solution to insulating an attic opening, however alternatively contemplated embodiments may be standalone devices. Further, cover 10 can be used to supplement the insulating value of other attic cover units, such as by way of non-limiting examples, a whole-house attic fan cover or an attic scuttle hole access cover.

In operation, a user must first prepare and ensure the attic floor 60 is level to accommodate rigid member 12. Rigid member 12 is placed on attic floor 60 such that bottom wall 12 f engages the floor 60 and top panel 12 a is upwardly facing. Cover 10 is placed over the top panel 12 a of rigid attic sealing member 12, or over the Therma-Dome®. The top 12 a of member 12 is aligned with cavity opening 38. Then a user applies a downward force to cover 10 so that member fits into cavity 40. The sidewalls 12 b-e frictionally engage inner sidewalls that define cavity 40. The rigidity of member 12 provides the base structure for the flexible embodiment of cover 10. In some embodiments, prior to fitting the cover 10 over member 12, an adhesive may be exposed so cover 10 sticks to member 12 when member 12 is nested within cavity 40.

Then a user fills cover 10 with insulation 46. When using roll insulation, a user may cut segments of the roll insulation to a desired length. As described above, a first set of two cut segments of roll insulation 46 have a width of about 15 inches and a length of about 62 inches. One of these two segments from the first set is inserted through slit 42 and maneuvered such that it is disposed between a sidewall 18 and inner wall 32 within the chamber 44. The second of these two segments from the first set is inserted through slit 42 and maneuvered such that it is disposed between sidewall 20 and inner wall 30 within the chamber 44. A second set of two cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 46 inches. One of these two segments from the second set is inserted through slit 42 and maneuvered such that it is disposed laterally between endwall 22 and inner wall 36 within chamber 44. The second of these two segments from the second set inserted through slit 42 and maneuvered such that it is disposed between endwall 24 and inner wall 34 within chamber 44. A third set of three cut insulation segments of roll insulation 46 have a width of about 15 inches and a length of about 78 inches. Each of the cut segments are inserted through slit 42 and maneuvered such that they are disposed longitudinally side-to-side and positioned below top panel 16 and above the first set, the second set, and the upper inner wall 28 within chamber 44. Alternatively, when using blown insulation 46, a user may insert a hose 48 through slit 42 and pump insulation into chamber until full.

Once cover 10 has been filled with insulation, the assembled system 1 is placed over the attic opening 14. Bottom wall 12 f engages attic floor 60 to create an air tight seal.

It is noteworthy that the present invention can be used to raise the insulative R-value of any space above an attic opening equal to that of the attic floor, not just a ladder for the attic access opening. The present invention may be broadly used with scuttle openings and any other openings to the attic regardless of their location, such as a side opening or a roof hatch.

In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed. Moreover, the description and illustration of the example embodiment of the invention are an example and the invention is not limited to the exact details shown or described.

The insulating system within an attic of claim 14, further comprising: a top panel and a bottom panel on the cover partially defining a chamber for filling with insulation; and an inner upper panel on the cover partially defining a cavity, wherein the sealing member is received in the cavity such that the cover caps the sealing member.
 16. The insulating system within an attic of claim 14, further comprising: a first insulating R-value of the sealing member less than about R-20; and a second insulating R-value of the cover greater than about R-20.
 17. The insulating system within an attic of claim 14, wherein the second insulating R-value of the cover is generally similar to a surrounding insulating R-value of an attic floor.
 18. The insulating system within an attic of claim 14, further comprising: a top panel on the attic sealing member; an upper inner panel on the cover partially defining a cavity for receiving the attic sealing member; and an engagement of the top panel with the upper inner panel when the cover is atop the attic sealing member.
 19. The insulating system within an attic of claim 14, further comprising: a sidewall on the attic sealing member; an inner sidewall on the cover partially defining a cavity for receiving the attic sealing member; and an engagement of the sidewall with the inner sidewall when the cover is atop the attic sealing member.
 20. The insulating system within an attic of claim 14, further comprising: a folded articulated attic ladder attached to an attic pull-down door in an attic opening; a nesting relationship with the cover receiving the attic sealing member within the cavity; and a sealing position wherein the cover nesting atop the attic sealing member rests above the folded attic ladder to seal and insulate the space above the attic opening.
